CAR FOR MOVING MATERIAL FROM TUNNELS.

Specification of Letters Patent.

' Patented Oct. 17,1916.

Application filed February 7, 1916. Serial N 0. 76,564.

To all whom it may concern:

Be it known that I, FREDERIC E. BAGER, a citizen of the United States of America, and resident of Kenosha, Kenosha county, Wisconsin, have invented a certain new and useful Improvement in Cars for Moving Material from Tunnels, of which the fol lowing is a specification.

My invention relates to dump cars for use in removing the excavated dirt from a tunnel during the operation of tunneling underground.

Generally stated, the object of my invention is to provide an improved dump car especially adapted for this particular purpose. More specifically considered, the object of my invention is to provide a dump car which will travel outward on one rail, thereby to carry the load to the mouth of the tunnel, which will then dump or discharge the load in a suitable or desired manner, and which will then return upside down on another rail to the inner end of the tunnel.

It is also an object toprovide certain details and features of construction and combinations tending to increase the general efiiciency and serviceability of a dump car of this particular character.

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawingsFigure 1 is a side elevation of a dump car embodying the principles of my invention, showing the same in carrying position on one of the rails of the tunnel. tion of the said tunnel, on a smaller scale, showing the said dump car in end elevation. Fig. 3 is a similar view showing the dump car in the position in which it is maintained while returning from the mouth of the tunnel to the inner end of the latter or the place where the dirt is being excavated.

As thus illustrated, the tunnel is preferably round in cross-section, as shown in Figs. 2 and 3, and is provided along the bot tom thereof with parallel rails A and -B which are spaced a suitable distance apart and which may be of any suitable charac-- ter.

Fig. 2 isa cross-sec- The dump car has a body C provided with a flat open top Q and a flat inner side wall 1, which latter extends at right angles to the sald top. The outer side 2 of said body is curved to enable the car to travel close to the side of the tunnel, and this side is provided with a door D of any suitable character, hinged at its upper edge at d to the upper portion of the body, whereby the eontents of the car may be dumped or dis-- charged in the desired manner.

The bottom of said body'is provided with front and rear wheels E which travel on the rail A while the caris moving with its load toward the mouth of the tunnel. The outer side of said body is provided with front and rear rollers F which travel on the sides of thetunnel, thereby to hold the car in carrying position. Said body is also provided with front-and rear wheels G which are carried on swinging legs 9, the latter being connected by links 3 with the brackets 4 on the ends of the body. Hooks H are pivoted on said legs at h and adapted at their other ends to engage the pins 5 on the ends of the body. Inthis way, the saidhooks supportthe wheels G in elevated positions while the dump car is traveling toward the mouth of turned upside down, as shownin Fig. 3, and

the wheels G are brought into engagement with the rail B, thereby to support the body in the manner shown. This may be accomplished by disengaging the hooks H from the pins 5 and then causing them to engage the pins I, the rollers F at this time engaging the other side of the tunnel. In this position, the dump car is adapted to travel back from the mouth of the tunnel to the place where the dirt is being excavated,

With this construction several dump cars can be traveling outward along the tunnel at the same time that several other dump cars are traveling or returning to the inner end of the tunnel, the outgoing cars freely passing the incoming cars. Each car, after reaching the mouth or outer end of the tunnel, is then transferred from the rail A to comprising a body provided with wheels for supporting it in carrying position on one of said rails, thereby to carry the load of dirt to the mouth of the tunnel, and provided with other wheels for supporting said body upside down on the other rail, the car on one track being adapted to pass a similar car on the other track when the body of one car is upside down and the body of the other car is in carrying position.

6. A dump car for use in a tunnel which is round in cross-section, and in which a tworail track is laid along the bottom thereof, comprising a body provided with wheels for supporting it in carrying position on one of said rails,'thereby to carry the'load of dirt to the mouth of the tunnel, and provided with other wheels for supporting said body upside down on the other rail, the car on one track being adapted to pass a similar car on the other track when the body of one car is upside down and the body of the other car is in carrying position, said other Wheels having articulated connections with the body, and the wheels which support the dump car in carrying position having axes of rotation which are fixed relative to said body.

7. YA dump car for use in a tunnel which is round in cross-section, and in which a two-rail track is laid along the bottom thereof, comprising a body provided with wheels for supporting it in carrying position on one of said rails, thereby to carry the load of dirt to the mouth of the tunnel, and provided with other wheels for supporting said body upside down on the other rail, the car on one track being adapted to pass a similar car on the other track when the body of one car is upside down and the body of the other car is in carrying position, said body having an outer side and bottom which are curved substantially like the adjacent surface of the tunnel, and the said outer side being provided with means for engaging the side of the tunnel to maintain the body in carrying position, and also in the upsidedown position. thereof.

8. A dump car for use in a tunnel which is round in cross-section, and in which a two-rail track is laid along the bottom thereof, comprising a body provided with wheels for supporting it in carrying position on one of said rails, thereby to carry the load of dirt to the mouth of the tunnel, and provided with other wheels for supporting said body upside down on the other rail, the car on one track being adapted to pass a similar car on the other track when the body of one car is upside down and the body of the other car is in carrying position, all of said wheels being in the same vertical plane when the body is upside down, and means whereby said other wheels occupy inoperative positions adjacent the bottom of the car when said body is in carrying position.

with other wheels for supporting said body upside downon the other rail, the car on one track being adapted to pass a similar car on the other track when the body of one car is upside down'and the body of the other car is in carrying position.

10. A dump car provided with a tilting body, wheels for supporting said body in carrying position, and means including other wheels for supporting said body in an upside-down position.

11. A dump car provided with a tilting body, wheels for supporting said body in a carrying position, and means including other wheels for supporting said body in an upside-down position, all of said wheels being in the same vertical plane when the body is inverted.

12. A dump car provided with a tilting body, wheels for supporting said body in carrying position, and means including other wheels for supporting said body in an upside-down position, said wheels all being adjacent the bottom of the dump car when said body is right-side up.

13. A dump car provided with a tilting body, wheels for supporting said body in carrying position, means including other wheels for supporting said body in an upside-down position, and means serving to laterally support said body in both positions thereof.

14. A dump car comprising a body provided with wheels to support the load only at one side of the center of gravity thereof, so that the car tends always to tip laterally toward the other side, and means on said other side of the body to travel on a suitable support and thereby hold the body in carrying position, said body having a curved outer side provided with a door hinged at its upper edge and also between the upper and lower edges thereof.

15. A dump car provided with a tilting body, wheels for supporting said body in carrying position, and means including other wheels for supporting said body in an upside-down position, said body having a curved outer side provided with a door hinged at its upper edge and also between the upper and lower edges thereof.

16. A dump car comprising a body provided with wheels to support the load only at one side of the center of gravity thereof, so that the car tends always to tip laterally toward the other side, means on said other side of the body to travel on a suitable support and thereby hold the body in carrying mounted to rotate about vertical axes.

17. A dump car COIDPI'lSlIlg a body provvvided With Wheels to support the load only at one side of the center of gravity thereof,

so that the car tends always to tip laterally toward the other side, means on said other side of the body to travel on a suitable sup- .port and thereby hold the body in carrying position, said means being disposed adjacent the top of the car and having lateral engagement With said support.

18. A dump car comprising a body prov'ided With Wheels to support the load only at one side of the center of gravity thereof,
